Abstract: Abstract of the Disclosure In order to reduce bias errors resulting from mounting of a force restoring coil assembly element of a force balancing transducer, the force coil assembly is suspended by means of one or more hinges from a force sensing movable member, which includes position pick-off means, that in turn is connected by hinging means to a support member.  The effects of strain may further be reduced by locating the first hinge element essentially along the axis of the centroid of the pick-off means.

Abstract: Abstract of Disclosure A line/interface circuit for a key telephone system, which system is of the type including a subscriber telephone line manifesting a pair of conductors.  The conductors emanate from a central office or PBX and the line/interface circuit pro-vides interconnections between a key subset associated with said subscriber and said central office via said telephone line.  The line/interface circuit has a photo-coupler for producing a signal indicative of ringing to indicate an incoming call.  A transistor and a first relay are coupled to the photo-coupler to access the subset with an alternate signal.  The subset is coupled for the transmission of voice signals to the telephone lines by means of a transformer to provide isolation.  Two further relays are provided to enable operation of the subset in a hold condition without releasing a connection between a connected party and the subset.  The line circuit provides a fourth relay to enable the subset to initiate a call by access-ing the telephone lines, which access is accomplished rapidly with a minimum of interferences in regard to the telephone lines.          Due to the nature of the coupling and operation of the line circuit, the line circuit performs all required switching and supervisory functions with a minimum of interference to the telephone lines, thus avoiding the use of an interface.

Abstract: ABSTRACT OF THE DISCLOSURE Sllyl ethers of 1,3-dicarbonyl cyclic compounds, such as methyl tris-5,5-dimethyl-cyclohexen-2-one-3-yloxy silane can be made by effecting reaction in the presence of an acid acceptor between an organo halosilane and a 1,3-dicarbonyl cyclic organic compound, for example, 5,5-dimethyl-1,3-cyclohexane dione.  The silyl ethers are useful as vulcanizing agents for silanol terminated polydiorganosiloxanes.  The curing time of the siloxanes can be varied according to the organo group of the organo-halosilane.  When this group is C(1-3) alkyl relatively rapid cure results.  When the group is C(4-12) alkyl or alkoxy, slower cure times result.

Abstract: ABSTRACT         The invention relates to a novel metabolite, M.139603, of the empirical formula C35H53O8Na, which is obtained from the aerobic fermentation of a novel Streptomyces species, NCIB 11426, and to the corresponding free acid form thereof, C35H54O8.  M.139,603 reduces the proportion of methans produced by the "digestion" of food in the rumen of ruminant animals and increases the proportion of propionate to acetate in the rumen contents.  The compound is therefore useful for increasing the growing rate of ruminant animals, and/or for increasing their efficiency of food conversion.  The compound also possesses activity against Gram positive micro-organisms, and against coccidia, for example Eimeria tenella.

Abstract: ABSTRACT OF THE DISCLOSURE        A transmission having a torque converter, lockup clutch, and a 5-speed planetary transmission having four planetary gearsets and six friction drive-establishing devices combined to provide five forward speed range drives having a large total gear ratio step, and a reverse drive having a moderate and a high gear ratio.  The 1st or primary gearsets with the primary input to the sun gear, the ring gear braked, and carrier output, provides 1st range drive having the largest torque multiplication gear ratio.  The 2nd, 3rd, and 4th gearsets, the secondary gearsets, are used to provide a secondary input having decreasing torque multi-plication gear ratios, to the ring gear of the 1st gearsets which, with the primary input to the sun gear, provides 2nd through 5th range drives having decreasing gear ratios.  The gear ratio steps between 1st, 2nd, and 3rd ranges are wide, and between 3rd, 4th, and 5th ranges are very close.  The automatic controls provide torque converter drive in a portion or all of 1st and 2nd range drives and in a portion of 3rd range drive up to a transition output speed, and lockup drive above the transition output speed in 3rd range drive and all of 4th and 5th range drives, to maintain engine speed within a small engine working speed range between the peak torque speed and maximum governed speed.

Abstract: ABSTRACT OF THE DISCLOSURE         This specification discloses systems for testing the integrity of bottles and the like by subjecting them to hydrostatic pressure as they move along a conveyor device and more particularly, to a bottle condition determination and reject means for such an on-line pressure testing system.  A sequence of substantially uniformly spaced bottles is conveyed through a preliminary filling apparatus which injects water into each bottle to its brim full capacity.  Thereafter, the filled bottles are carried at a predetermined rate and spacing such as by a screw conveyor or the like, past a hydrostatic test head station at which a hydrostatic test heat is synchronously reciprocated to engage and seal with the open top, at the brim, of each successive bottle.  The hydrostatic test head applies a downward force to the continuously moving bottle at the brim or sealing surface thereof, with a force sufficient to contain hydrostatic pressure which is subsequently applied to the interior of the bottle after the seal between the hydrostatic test head and the brim of the bottle is effectuated.  The bottle is then subjected to a prescribed internal hydrostatic pressure for a prescribed time interval or test cycle, from a suitable source of hydrostatic pressure such as a high pressure water pump which feeds pressure fluid to the interior of the bottle through the hydrostatic test head. A pressure sensing tube and sensing assembly are provided in the hydro-static test head immediately adjacent to the sealed brim area of the bottle to transmit the resultant internal hydrostatic pressure in that bottle under test to a pressure transducer device serving as an input to a selective reject mechanism.

The transceiver is housed in a light tight housing and includes an adjustable mirror offset from the active element of the transceiver.  The mirror directs light through an aperture in the housing along a predetermined axis from the active element and directs light to the active element which is received through the aperture along the axis.  The mirror deflects any light received through the aperture which is received at an angle greater than a predetermined angle from the axis around the active element of the transceiver to block ambient light interference.  The transceiver also may be utilized in an improved light screen or barrier which may be utilized either for an alarm system such as in a jewelry case or in a counting system wherein objects are passed through the light screen in the frame to be counted.

Abstract: TRACKING APERTURE RADAR          ABSTRACT OF THE DISCLOSURE          The transmitting antenna of a side looking radar system for high flying aircraft and space vehicles emits radar pulses which illuminate a narrow patch of terrain which is elongated in a direction orthogonal to the direction of progression of the vehicle carrying the radar system.  Reflected pulses are received in a receiving antenna which illuminates an area contained within the patch and has the width of the patch but a small fraction of its range extent.  The patch is scanned with the receive area. By the use of this system, for a given antenna size the previous transmitter power dependence on frequency is avoided, thus allowing much higher R.F. frequencies to be used with available transmitter power.
